Clarifying lysosomal storage diseases.

ABSTRACT: Lysosomal storage diseases (LSDs) are a class of metabolic disorders caused by mutations in proteins critical for lysosomal function. Such proteins include lysosomal enzymes, lysosomal integral membrane proteins, and proteins involved in the post-translational modification and trafficking of lysosomal proteins. There are many recognized forms of LSDs and, although individually rare, their combined prevalence is estimated to be 1 in 8000 births. Over two-thirds of LSDs involve central nervous system (CNS) dysfunction (progressive cognitive and motor decline) and these symptoms are often the most debilitating. Although the genetic basis for these disorders is clear and the biochemistry of the proteins well understood, the cellular mechanisms by which deficiencies in these proteins disrupt ne
